DeepRails is a production AI reliability platform built for teams that cannot afford wrong answers. We provide two core services that work together to ensure your AI applications remain accurate, safe, and trustworthy throughout their lifecycle — across healthcare, legal, financial services, education, and any domain where output quality is mission-critical.

Monitor

Continuously monitor your AI applications for hallucinations, quality regressions, and performance drift in production.

Defend

Catch hallucinations in real time and automatically correct them before they reach your users.
Additionally, the intuitive DeepRails Console provides a central dashboard to visualize and explore evaluation data, manage defend workflows and monitors, and configure guardrails efficiently.

The Challenge - Evaluating Model Performance

“Lack of evaluations has been a key challenge for deploying to production”
- OpenAI, DevDay Conference
AI systems can generate significantly varied outputs for identical inputs, complicating benchmarks and making consistent evaluation difficult. Current evaluation methods struggle to identify subtle inaccuracies, hallucinations, or early indicators of performance drift, exposing organizations to critical risks. Additionally, as models evolve, previously reliable methods quickly become obsolete. This requires the need for evaluation tools that keep pace with continuous changes in AI behavior to consistently provide trustworthy insights and guardrails against critical failures.
”.. don’t consider prompts the crown jewels. Evals are the crown jewels”
- Jared Friedman, Y Combinator Lightcone Podcast
The best performing prompts are guided by continuous rounds of high quality evaluations.

​
What Makes DeepRails Unique

Most AI safety tools stop at detection: they flag problems, block outputs, or log failures for you to handle later. DeepRails goes further. The Defend API corrects hallucinated responses automatically, so your users always get accurate answers.
  • Monitor API: Real-time detection and observability across your production AI outputs
  • Defend API: Real-time detection + automatic correction, verified before delivery
In independent benchmarks against AWS Bedrock Guardrails, DeepRails is 45% more accurate on correctness and 53% more accurate on completeness. Your AI applications self-heal in production, reducing support tickets, compliance risk, and user frustration.

How DeepRails Works

DeepRails delivers highly performant research-driven metrics, continuous monitoring capabilities, and real-time guardrails designed specifically for mission-critical AI applications. Our Guardrails guide both our proprietary Multimodal Partitioned Evaluation (MPE) engine and our one-of-a-kind remediation service for AI hallucinations. Each guardrail was selected based on years of generative AI experience and rigorous research. The most important metrics are included first, and more are being designed by the DeepRails team continuously. As part of development, each Guardrail has a Multimodal Partitioned Evaluation prompt individually created and tested. MPE prompts outperform other evaluators by breaking inputs down into granular chunks before evaluating and then aggregating scores.
